'TOBACCO-CURING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 264,141, dated September 12, 1882.

Application lled January 3, 1881.

To all whom it may concernJ Be it known that I, yCHARLES E. DOYLE, a citizen ofthe United States, residing atNo. 335 South street, in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and, useful Sweat-House for Sweating, Coloring, and Curing Tobacco, of which the following is a specification.

My invention relates to sweating, coloring, and curing tobacco; and the nature thereof is in providing certain construction in and to sweat-houses for the purpose of sweating, curing, and coloring tobacco; also, in a certain construction for the purpose of economy in the heat used in the operation of curing tobacco.

In all thegures thesame letters of reference refer to the same parts. By reference to the drawings and letters of reference marked thereon a full and clear understanding of this invention will be given, aided by this specification.

In the drawings, Figure 1 isa side elevation of my sweat-house. Fig. 2 is a sectional side elevation of my gas-regulator.V Fig. 3 is a sectional elevation of Fig. 1. Fig. 4 is a crosssection of Fig. 1. Figs. 5, 6, and 7 are detailed parts of the heating apparatus.

The sweat-house E is divided into an upper, I, and lower, E, compartment. Theupper compartment, I, is divided from the compartment E by a sheet of metal, u', forming the bottom of I, which is held up by cross-pieces p, and is provided with as many cross-.pieces as will be necessary. rlhe compartment I is closed in by the door a, fastened by the clutch or catch b. In thecompartment E, at the bottom thereof, are the grooved ways m', forming a track or way for the wheels sof the truck C to run in, guiding the said wheels s into the compartment E. The bottom board, S, has the pan c let into the thickness of the bottom board, S, and will hereinafter be more fully described. The compartment E is closed by the door A. The bottom board, S, has the iuclines c and grooved ways m', and this projecting incline c and grooved ways give a sloping entrance to the compartment E. The door A rests or is screwed to the piece q. At the back of the compartment E is the box m, from which is led the bent pipe u. This pipeu is for the purpose 0f conveying water from box m to the (Model.)

pan w and shutting off the iiow by the stop e of spring o, closing the opening y of pipe u. The spring lv is held in position on the pipe u by the band and set-screw w. Resting on the spring o is the rods of the shaftw. lIhis shaft rests in journals u2 and a3, and is projected through the side wall of the compartment E to a second rod, o. This rod o rests in a groove, z', of a weighted rod, z2, which-operates the gas-valve z3. It is clear that when the spring o rises the rod o also rises, turning on the gas through the action of rods and shaft te', opererating and relieving the weighted rod z2 of valve z3, causing the weight to drop, leaving the gas turned oft. Ihere is a check on the gas-pipe e by valve h', operated by the rod g of the regulator d. The regulator d is at the side of the` sweat-house, and has a pipe, f, which is projected into the compartment E. rlhis regulator operates as follows: When there is pressure in the compartment E of steam the rubber cover a' is forced downward and carries rod g, to which it is attached, in the downward direction. The enlargement of pipef at regulator d faces downward, as shown at n', and has the hole denoted by the arrow, Fig. 2. Forced onto the lower end of the regulator d is a rubber cover, c', and to the center of this cover is attached the rod g. In the middle of this rod gis the regulatingnut g2. The rod g, regulated to p'roper length, engages at k with the valverod h and valve h of the gas-pipe c. When the steam has expelled the air from the compartment F.,and,cooling, leaves a partial vacuum, the gum cover a is drawn up and in and the rod g is drawn up, pulling up rod h and opening the valve h', turning on the gas to again make steam. The interior b of the regulator d is partially filled with water to protect the rubber cover a from direct contact with the hot air which is contained in the pipe f when the sweating apparatus is in operation.

Four thin tubes, c, are placed at the corners A of the compartment E, for the purpose of admitting near the bottom E a small quantity `of air to cause a diffusion of the hot air up- ICO ward in the apparatus, at the same time supplying air for tbe burner o. At; the side of the compartment E are peep-holes i, closed by the sliding doors fn. The pan e is filled with Water, and is provided with a central opening, through which passes burner 0.

The operation of the invention is as follows: rlhe tobacco to be operated upon is placed on the truck U, which is run into the compartment E. The doors are closed up tightly. The pan w is filled with Water, and the same is stopped off from the How by its own weight, as hereinbef'ore described, the gas having been previously lighted at burner o before closing up the compartment. The Water in pan 'w is heated, giving oit' its steam, and as the water evaporates the pan lightens and again fills, as before set forth, and the steaming process carried out, fully curing the articles placed in the case. Rod g, with rod s, as hereinbef'ore stated, regulates the gas-dame.

Having thus described the construction and operation of my invention, what I claim as mine, and desire to secure by Letters Patent of the United States, is as follows:

l. The suspended pan fw, operating the spring 1J ot' the water-pipe u, in combination with a resweatingcompartment, as and for the purposes specified.

2. The pan e for Water, provided Wit-l1 the central burner7 0', supplied with gas to heat a compartment for resweating tobacco, substantially as setl forth, and operating, in combination with the suspended pan w, for the purpose described.

3. The combination ofthe suspended pan w with the spring v, attached to the pipe u, connected to the reservoir m, substantiall)- as and for the purposes seb forth.
